National tensions in what region led to the outbreak of World War I?

• A. The Balkans
• B. The Middle East
• C. The Far East
• D. South America

Answer: (A)

Nationalism and ethnic tensions in the Balkans created a volatile hotspot in Europe that helped spark World War I. Diverse groups in the region sought independence or unification, heightening instability inside Austria-Hungary and provoking rival powers. The immediate trigger was the assassination of Archduke Franz Ferdinand in Sarajevo, which set off a chain reaction of alliance-based mobilizations. Because Europe’s powers were bound by treaties, a regional crisis in the Balkans quickly escalated into a continental war and then a global conflict. Other regions mentioned did not ignite the same crisis that turned a regional powder keg into World War I.
